摘要:
A method and unit for feeding blanks to a user machine, whereby at least two synchronized pickup heads withdraw the blanks from respective hoppers and feed them to respective conveying pockets moving continuously along a user path of the machine; each blank adheres by suction to a flat conveying surface of the respective pickup head, with a first lateral edge projecting outwards of the flat conveying surface and with a second edge contacting a push tooth projecting from the respective flat conveying surface, and is so inserted inside the respective conveying pocket as to be maintained in a flat configuration between the push tooth and a stop element moving together with the conveying pocket.

A method of forming groups of cigarettes, each group being defined by at least one layer of cigarettes arranged side by side. The layer is fed continuously at a given speed and by means of a conveying seat along a given annular path extending through an unloading station. At the unloading station where the layer is transferred from the seat to a group forming pocket (6) by orienting the seat with respect to the path as a function of the relative position of the seat and the pocket (6) at least at the unloading station.
摘要:
A packing machine for producing semi-finished packets of cigarettes having respective blanks of packing material and respective wrappings, wherein a forming drum rotates continuously about a given axis to form the packets by partially folding the blanks about the respective wrappings; the drum being located along a packing path having an input branch, an output branch, and an intermediate branch defined by the drum and extending substantially in a spiral about the given axis; the input branch and the output branch being straight and tangent to the intermediate branch; and the drum having a number of orienting assemblies for feeding the packets to the output branch with respective longitudinal axes of the packets oriented parallel to an output direction.
摘要:
A method and unit for feeding collars for packets of cigarettes to a continuous packing line, whereby the collars, picked up successively and in steps by a transfer device, are transferred rapidly by the transfer device to a continuously-moving supply assembly, which feeds the collars successively to the packing line after squarely folding two lateral wings of each collar; the collars being fed on to the packing line with the lateral wings crosswise to a traveling direction of the line.
摘要:
The unit for forming groups of cigarettes has at least one substantially U-shaped pocket designed to receive in succession at least two layers of cigarettes, in which the cigarettes are parallel with a longitudinal axis of the pocket, the two layers being arranged one above the other to define a respective group; the unit having at least one holding element and, if the group has at least one gap, the unit having at least one dummy positioned parallel with the axis, both being mobile, under the thrust of an actuator, between a home position and an operating position, in which the element and the dummy are positioned respectively outside and inside the pocket, to respectively lock the group of cigarettes within the pocket, and to compensate the gap.
摘要:
Products are transferred from a first conveyor to a second conveyor along a set feed path by a device including a pressurized pneumatic duct interposed substantially with no break in continuity between the outfeed end of the first conveyor and the infeed end of the second conveyor. The pneumatic duct is connected to a source of compressed air, which is admitted convergently with the feed direction and at a velocity and rate of flow such that the products are invested with movement by fluid power alone and caused thus to pass along the duct toward the infeed end of the second conveyor.
摘要:
A device for applying sealing labels to containers defined partially by two parallel faces and by a further face connecting the two parallel faces; the device including a conveying device for feeding containers to a labeling station, and a supply device for supplying labels and presenting at least one retaining device for retaining two opposite end portions of the label; the conveying device consisting of a conveyor for successively conveying the containers with the further face downstream in relation to the traveling direction of the conveyor; and an actuating device being provided for moving the retaining device between a position, assumed at least at the labeling station, of interference with the path of each container on the conveyor, and a position of noninterference with the aforementioned path.
摘要:
In a cigarette packet that consists of a single wrapper with an easy opening tear ribbon, applied to the inside surface, the wrapper exhibits break lines coinciding one with each longitudinal edge of the ribbon, and incisions positioned to coincide with the opposite ends of the ribbon; also applied to the inside surface of the wrapper, at least over the areas exhibiting the incisions, are respective ribbon patches able to restore the continuity of the wrapper where broken by the incisions, in such a way that the contents of the packet will remain isolated from the external environment until the ribbon is removed.
摘要:
Seal labels are affixed to containers by means of equipment comprising a system of conveyors serving to direct a succession of the containers along a predetermined path, and a feed device by which gummed labels are supplied to a fixing station occupying a position alongside one part of the selfsame path. The feed device affords a recess located between two points against which the two ends of each label are restrained, and operates in conjunction with a first push rod by which each container in turn is displaced from the conveying path, directed forcibly against a relative label supported by the device and caused to penetrate the recess to a given depth together with the label. Thereafter, the container is ejected from the recess and repositioned on the conveying path by a second push rod.
摘要:
An output conveyor unit for rigid hinged-lid cigarette packing machines, whereby a first conveyor, consisting of a packing wheel, successively feeds the semifinished packets to respective seats on a drying conveyor, each seat having a movable wall which is moved by an actuating element as the packet is inserted inside the seat, and then released for axially compressing the packet and maintaining it in the correct drying position.
